Effect of Daily Milk Supplementation on Serum and Umbilical Cord Blood Folic Acid Concentrations in Pregnant Han and Mongolian Women and Birth Characteristics in China
並列摘要
Many studies have demonstrated the efficacy of folic acid (FA) supplementation in prevention of neural tube defects (NTDs), although the extent of NTDs varies among individuals of different races and ethnic origin. China is a multi-ethnic country with no standard practice for FA-fortified food. Milk is consumed by women, but little is known about the effects of milk on folate concentration in maternal blood and neonatal umbilical cord blood in Han and Mongolian women after stopping taking the supplement for a month and five month, respectively. The objective of this study was to determine whether only daily consumption of liquid milk can increase the blood folate concentration in pregnant women and whether there are differences in blood folate concentrations between Han and Mongolian women after cessation of FA supplementation. Of the 4052 women enrolled in the cross-sectional study. Three thousand five hundred and twenty-six women had confirmed pregnancies and were randomized to receive liquid milk or not until delivery. Women who consumed the liquid milk had significantly increased serum folate concentrations at 16 and 32 weeks of gestation as well as cord blood at birth compared to control groups in both ethnic groups. Infants born to women drinking milk also had better the term birth weight and height, which may be related to the increased concentration of folate. In conclusion, daily consumption of milk can increase the serum folate concentration in pregnant Han and Mongolian women in China (differences in the efficacy of FA and milk supplementation) and may enhance birth outcomes.
